lund tune issue

[kcc0521]

I just installed the jlt and lund tune on my 2015 pp gt. The install and tune download went smoothly until I started the car. The car was idling rough and the check engine light came on when I drove it. I returned the car to stock and it runs fine. Did anyone else have this issue?

I'd try downloading again.

Did you update the tuner before loading the tune?
Are you sure you installed the intake properly? Double check everything you touched under the hood.
Did you check what the cel was for?

Try installing the intake again and reloading the tune, assuming you did the update.

Has anyone had an issue where down loading the tune again worked? Do you mean download from the tuner to car or download tune to the tuner then to the car?

I did update the tuner.

I mean when car is returned to stock, just download performance tune again.

As mentioned above, did you pull the code with the xct? And make sure the intake was installed properly and the maf reconnected properly?

Sure sounds like a large vacuum leak.

When you say put it back stock, you reinstalled the stock intake? Or did you leave the jlt and just load stock tune in?

When you say you returned to stock, I'm guessing you put the stock intake back on? Ask Lund to check your tune, I had this same problem, contacted TBR and turned out I got sent a tune for the stock intake, no CAI. You may have the same problem I did.

I had a similar issue - car would never return to idle. Would stay up at a high IDLE....Open a ticket on LUNDS website and they will respond. Both ken and John got me fixed. In the end I ran a log and sent it in. The file got corrupted via email. John resent it it a zip format and bingo, everything is fine

When things like this happen you need to do a few steps before posting on a forum. Read the code, and tell us what it is. See if you can address the code on your own. Contact Lund with a trouble ticket.

I did not data log and I returned the car back to stock. I am sorry for the quick post but I am trying to get the car ready for the track tomorrow. I put a ticket into lund and I am hoping to get the tune fixed. I am fairly certain there was not a vacuum leak. Does anyone have a number to reach out to lund directly? How long did it take to get the revised tune via ZIP?

Lund replied to me instantly when I had questions. Contact your vendor and maybe they can get things moving a bit quicker for you.

Where in Falls Church are you? I work in Tysons and maybe I can swing by after work if you still need a hand. I get out usually around 5pm. Do you have a battery charger?

First thing too is to make sure you 100% loaded the custom tune, and not a canned sct

I shot you an email as well on mod list, but make sure it is the tune file I emailed to you
